Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. A palm vein imaging device that includes a housing, at least one imaging sensor for capturing images of palm veins, an optical imaging system, light emitting elements and a controller, wherein the palm vein imaging device contains an infrared transmission filter and a scattering filter installed above the light emitting elements and the light emitting elements are infrared light-emitting diodes emitting light of wavelength of 850 nm and 940 nm, wherein the light-emitting diodes are placed around the optical imaging system so that the light-emitting diodes emitting light of wavelength of 850 nm are placed in between light-emitting diodes emitting light of wavelength of 940 nm.
2. A palm vein imaging device of claim 1 , wherein the palm vein imaging device contains eight infrared light-emitting diodes with wavelength of 850 nm and eight infrared light-emitting diodes with wavelength of 940 nm.
3. A palm vein imaging device of claim 1 , wherein the controller includes at least a central processing unit and memory.
A palm vein imaging device captures and processes images of a user's palm veins for biometric authentication. The device includes an imaging unit that emits near-infrared light to illuminate the palm and a sensor to detect the reflected light, generating an image of the vein pattern. A controller processes the image to extract biometric data for identification or verification. The controller includes a central processing unit (CPU) and memory, which store the captured images and execute algorithms to analyze vein patterns. The device may also include a communication interface to transmit data to external systems for further processing or authentication. The imaging unit is positioned to ensure consistent alignment with the user's palm, and the device may incorporate additional features such as a display for user guidance or feedback. The system is designed to operate in real-time, providing quick and secure authentication by comparing captured vein patterns against stored templates. This technology addresses the need for secure, non-invasive biometric identification in applications like access control, financial transactions, or healthcare.
4. A palm vein imaging device of claim 1 , wherein the infrared transmission filter at the same time is an upper case of the housing.
A palm vein imaging device captures infrared images of a user's palm to authenticate identity. The device includes an infrared light source to illuminate the palm, an infrared camera to capture the vein pattern, and an infrared transmission filter to block visible light and enhance vein contrast. The filter is integrated as the upper case of the housing, serving both as a protective cover and an optical component. This design reduces the number of parts, simplifies assembly, and ensures precise alignment of the filter with the camera. The housing may also include a palm placement guide to ensure consistent imaging. The device processes the captured vein pattern to generate a biometric template for authentication. This approach improves durability, reduces manufacturing costs, and maintains high imaging accuracy by eliminating separate filter components. The integrated filter design ensures optimal light transmission while protecting internal components from environmental factors. The device is used in security systems, access control, and financial transactions where reliable biometric authentication is required.
5. A palm vein imaging device of claim 1 , wherein the palm vein imaging device contains printed circuit boards installed horizontally in the upper and lower parts of the housing and connected together by means of connecting plugs.
6. A palm vein imaging device of claim 1 , wherein the palm vein imaging device contains a printed circuit board installed horizontally in the upper part of the housing with light emitting elements and electronic components to control the light emitting elements mounted to it.
7. A palm vein imaging device of claim 1 , wherein the palm vein imaging device contains a printed circuit board installed horizontally in the lower part of the housing with at least the at least one imaging sensor, a central processing unit and memory mounted to it.
8. A palm vein imaging device of claim 1 , wherein the palm vein imaging device has a USB interface.
